EXTE NSION-TABLE Specification of Letters Patent.

Patented July 9, 1907.

Application filed May 15,1906. Serial No. 316,941. I

To all whom it may concern:

Be it known that I, SAMUEL W. WHONN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification.

My invention relates to improvements in extensiontables, and has for its object the provision of a table of this character which may be quickly and readily ex tended or opened to receive additional leaves or panels, and which will be of compact and rigid construction.

Another object of my invention, is to provide a table consisting of but few and simple parts, and one which will be extremely durable and practical for all purposes.

My invention further consists of a table embodying certain other novel features of construction, combination and arrangement of parts substantially as herein set forth.

Figure 1., is a perspective view of my improved extension table with portions broken away to show the worki ing parts. Fig. 2, is a sectional view through the supporting bars taken on line 2--2 of Fig. 1. Fig. 3, is a detail perspective view of the supporting rollers and channel bar. Fig. 4 is a top plan view of a modified form of corner-bracing construction.

Referring to the drawings: the numeral 1 designates the frame of a table, provided with the supporting posts or legs 2. Extending the full length of the frame, are the two pairs of parallel guide or supporting bars 3, and in these bars at spaced intervals, are mounted the screw bolts 4. Upon these bolts, are mounted the sleeves or bushings 5, and upon said bushings, are rotatably secured the supporting rollers or pulleys 6. The periphery of the rollers is grooved, and in said groove fits a ring or washer 7. This ring may be of rubber, leather or similar material, and serves to deaden the sound and insure steady movement of the rollers. Mounted back to back, between the pairs of supporting bars, are the channel bars 8, having the flanged edges 9, so that the rollers are entirely inclosed within said bars. The upper edge of the channel bars is flush with the table frame, and to said bars, are secured the table leaves or panels 10. The ends of the table frame are cut away as at 11, to allow the passage of the bars therethrough, so that the panels may be extended as desired to allow the insertion of extra leaves therebetween. The supporting bars and channel bars may be constructed of wood or metal as desired, and when so constructed of metal, the ends 12, of the supporting bars, are bent over or upset as shown, for securing the bars in place. Diagonal braces 13, are secured in the corners of the frame, and a headed bolt 14, engages a longitudinal slot 15, in the post and passes through said brace. An adjusting nut 16, is mounted onthe end of the bolt, so that by this means the posts may be rigidly and adjustably secured in place. The brace just described is constructed of metal, but when a wooden brace is to be used, I employ the construction shown in Fig. 4. In this construction, the ends of the frame members form tongue and groove connection with the post as at 17, and the ends of the brace are beveled to properly engage the frame members. Securing pins 18, pass through the brace and frame, and the meeting edges of the brace and frame are mortised to receive a key or block 19. The adjusting bolt is used in connection with the post as before, and a rigid construction of the corner is thereby provided.

From this description taken in connection with the drawings, it will be evident that I have provided a substantial and durable table which is practical and efficient for the purposes set forth.

I claim:

1. A table comprising a frame, spaced metallic bars mounted lengthwise therein having angularlybent securing portions on their ends, there being slots formed in the frame between the ends of the parallel bars, bolts passing through the bars, headed bushings mounted on said bolts on the opposing faces of the bars, rollers mounted on the bushings and having countersunk face portions en gagecl by the head of the bushings, the rollers having a circumferential groove formed therein, resilient rims confined in said grooves, metallic flanged channel bars mounted back to back between the parallel bars with their flanges inclosing the rims on the rollers, and table leaves secured to the channel bars.

2. A table comprising a frame, spaced parallel bars mounted lengthwise therein, the frame having slots formed therein between the ends of the bars, bolts passing through the bars, headed bushings mounted on said bolts, rollers mounted on the bushings having countersunk face portions to receive the head of the bushings, resilient rims on the rollers, flanged channel barsmounted back to back between the parallel bars with their flanges inclosing the rims on the rollers, and table leaves secured to the channel bars.

In testimony whereof I aflix my signature in presence of twowitnesses.
